I created second accaunt for domain juandon.rf.gd, control panel and FTP works, but http://juandon.rf.gd redirects to Facebook.
When did you create the domain? If it was a few days ago, you may need to wait for DNS propagation.
In CP FTP address 220.127.116.11 equals to domain IP when oinging domain.
I flushed DNS cache, now ok, thanx.
